Hey all,
I need to do a bumper repaint after some sticker removal gone bad. It's been like this quite a while and I'm finally getting around to doing something about it. The car is no where near pristine so the results only need to be decent.
I was thinking some kinda of paint remover, then scuff, prime, and paint. Probably a single stage paint for ease of use.
Any and all suggestions welcomed.

Picture linky no worky. Most cars have two stage paint these days. If it's got metallic in it, you'll have to go 2 stage to even get the same color. If you have to remove the paint completely, some form of stripper (the liquid kind) is probably best. Sanding it off usually does more damage. Then scuff, prime and paint as you said. It may be a good idea if the bumper is 'raw' to use some adhesion promoter in your primer. Some will also make a big deal about flex additived on bumpers but you can get away without it.
Is this it?
I've used some stuff from Eastwood called Adhereto; it makes anything stick to anything.

Yup, that's it. I guess I needed html code, not board code for pics.
The paint isn't metallic, so that shouldn't be a problem. I want to take it all the way down as there are other problem areas on it that I don't want to pop up after painting it.
I figured on having a flex agent add to the primer and paint. I didn't think about an adheasion promoter, I'll add that to the list.
Yeah. You definitely need the flex stuff. And I do not think I can possibly be clear enough on how CLEAN the are must be. Clean clean clean! If you prepare it on day one and go back on day two to paint, CLEAN IT! If you don't, you'll end up with a bumper like the one on my Z3 where all the paint bubbled up and fell off 6 months after I bought it.
Some paint stores have Bulldog brand adhesion promoter in a spray bomb. And you may find a spray bomb of clearcoat, if you're lucky (don't use the Duplicolor stuff--find a professional brand). Many clears (and colors) don't need flex agents.
Clean, scuff, clean again, spray adhesion promoter, paint and clear.
If it's just plain black, don't bother with the clear. Just paint it black (you weren't going for show car quality from what I read). Yeah, I'd strip that thing fully and use adhesion promoter. Looks like the last guy who painted it didn't.
I'd:
Strip it with aircraft remover - aerosol.
Wash / dry it
Scuff with grey scotchbrite
Wipe it with 50% water, 50% rubbing alcohol (kills static, picks up oils)
Spray two coats of bulldog - aerosol
Shoot of a coat of epoxy
Shoot two or three coats of single stage acrylic urethane - no flex agent.
I agree with the comment about the Duplicolor clear in the rattlecan. The results I got were less than adequate.
DO NOT USE AIRCRAFT PAINT REMOVER
SEM and Bulldog make a paint remover for urethane bumpers.
1) SEM Bumper Stripper
2) Clean with SEM Scuff & Clean and a gray/ red scuff pad.
3) Clean with Comet and wax and grease remover. If the water beads up like a waxed car or just disappears off the plastic, clean it again. Keep cleaning until the water stays in one spot for a while.
3) Apply 2 light coats of adhesion promoter
4) Apply 2 medium coats of flexible primer sealer
5) Apply flexible primer surfacer and guide coat and sand with 320 grit
6) Apply color and clear coats
I used the duplicolor clear on a bumper and it wasnt too bad. The way I got it smoth was to spray 2 or 3 coats, sand it smooth with 1500 grit sandpaper, then spray a thin coat ontop. It just depends on how perfect you want it to be though. In my case, the bumper i painted with the rattle can paint is the best paint on the whole car. lol
Thanks for all the info. Now I just need a free weekend to do it.
Couple GRM bumper stickers? Sorry I am only here for comic relief.
honestly I wouldn't strip it at all. I'm attending Collision Repair and Refinishing at the local Tech School here in Chipley, Fl. What I would do is: 1. Remove the Rear bumper and wash it with a good soap solution 2. wetsand and featheredge the area where the paint is peeling and remove any other loose paint. 3 Use a paint stick with 400 grit sandpaper wrapped around it and block the primer down smooth 4.use a good quality primer and then lightly mist the Bulldog Adhesion Promoter then topcoat with a single stage urethane.
Where are you located?
Here's a pic of one of my project I had at school
